clump weight

Counterweight iron is a process of melting metal into a liquid meeting the requirements and pouring it into the mold. After cooling, solidification and cleaning, it is deeply affected by casting with predetermined shape, size and performance. Counterweight iron is one of the basic technologies in modern machinery manufacturing industry.

The precision of casting and the economic effect of the whole production process are mainly determined by this process. In many modern counterweight iron workshops, the core making of modeling has been mechanized or automated. The common sand mold core making equipment includes high, medium and low pressure molding machines, sand throwing machines, box less injection molding machines, core shooting machines, cold and hot box machines, etc. After the casting is taken out from the casting cooling mold, there are gate, riser and metal burr and burr. The castings of sand type counterweight iron are also bonded with sand, so it needs to be cleaned. The equipment for this work includes shot blasting machine, gate riser cutting machine, etc. Sand dropping cleaning is a process with poor working conditions. Therefore, when choosing molding method, it is necessary to consider creating convenient conditions for sand falling cleaning.
